Meet the Medical Director: Professor Claire Harrison
Professor Claire Harrison is one of the world’s leading experts in myeloproliferative neoplasms (MPNs) and the driving force behind MPN Voice.
A graduate of Oxford University Medical School, Claire became a consultant at Guy’s and St Thomas’ Hospital in 2001, where she now serves as Deputy Chief Medical Officer. Her clinical focus is MPNs, and her work has shaped the global landscape of treatment and research.
Claire’s leadership in clinical trials and translational research has contributed to the approval of several groundbreaking therapies, including ruxolitinib, fedratinib, momelotinib, and pacritinib. Over the past decade, she has published more than 300 academic papers, earning national and international recognition for her contribution to the field.
But Claire’s impact extends far beyond the clinic. She founded MPN Voice (MPD Support as it was) alongside a group of volunteer patients who shared her vision to ensure that everyone living with an MPN has access to accurate information, compassionate support, and a strong community.
Outside of her professional achievements, Claire is a proud mum to Henry and Edward, and she’s passionate about food, family walks, and time spent outdoors. Her warmth and energy reflect the same values that drive MPN Voice connection, care, and community.
Her work continues to inspire both patients and professionals, reminding us that progress in medicine is most powerful when it’s rooted in partnership.
